mysidia writes "A total of 16,777,216 IP address numbers were just allocated to the Asian Pacific Network Information Centre IP address registry for assignment to users.

Some venerable IP addresses such as 1.1.1.1 and 1.2.3.4 have been officially assigned to the registry itself temporarily, for testing as part of the DEBOGON project.

The major address blocks 1.0.0.0/8 and 27.0.0.0/8, are chosen accordance with a decision by ICANN to assign the least-desirable remaining IP address ranges to the largest regional registries first, reserving most more desirable blocks of addresses for the African and Latin American internet users, instead of North America, Europe, or Asia.

In other words: of the 256 major networks in IPv4, only 24 network blocks remain unallocated in the global free pool, and many of the remaining networks have been tainted or made less desirable by unofficial users who attempted an end-run around the registration process, and treated 'RESERVED' IP addresses as 'freely available' for their own internal use.

This allocation is right on target with projected IPv4 consumption and was predicted by the IPv4 report, which has continuously and reliably estimated global pool IP address exhaustion for late 2011 and regional registry exhaustion by late 2012.
